DESCRIPTION AND OPERATION
Supercharger Cooling
CAUTION: Some vehicle cooling systems are filled with Motorcraft Premium Engine
Coolant VC -4-A (in Oregon VC- 5, in Canada CXC- 10) or equivalent meeting Ford specification
ESE- M97B44- A (green color). Others are filled with Motorcraft Premium Gold Engine Coolant
VC -7-A or equivalent meeting Ford specification WSS- M97B51-A1 (yellow color). Always fill the
cooling system with the same coolant that is present in the system. Do not mix coolant types.
NOTE: The addition of Motorcraft Cooling System Stop Leak Pellets, VC- 6, darkens Motorcraft
Premium Gold Engine Coolant from yellow to golden tan.
NOTE: The air that is produced from the supercharger is cooled by the intercooler.
Walter C. Avrea, the owner of patents 3,601,181 and RE 27,965, has granted Ford Motor Company
rights with respect to cooling systems covered by these patents.
The cooling system components include the:
zintercooler
z intercooler radiator (8K226)
z pressure relief cap
z degas bottle
z electric water pump (8501)
The degas bottle:
zprovides a location for system fill.
z contains coolant expansion and system pressurization.
z provides air separation during operation.
z replenishes the intercooler coolant to the system.
The intercooler coolant flows:
zfrom the intercooler to the degas bottle.
z from the degas bottle to the water pump.
z from the water pump to the intercooler radiator.
z from the intercooler radiator to the intercooler.
Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to
the engine and cooling components. In order to obtain these protections, the engine coolant must be
maintained at the correct concentration and fluid level in the degas bottle.
When adding engine coolant, use a 50/50 mixture of engine coolant and clean, drinkable water.
To maintain the integrity of the coolant and the cooling system: SECTION 303-

DIAGNOSIS AND TESTING
Supercharger Cooling
Inspection and Verification
WARNING: Never remove the pressure relief cap while the engine is operating or when the
cooling system is hot. Failure to follow these instructions can result in damage to the cooling
system or engine or personal injury. To avoid having scalding hot coolant or steam blow out of
the degas bottle when removing the pressure relief cap, wait until the engine has cooled, then
wrap a thick cloth around the pressure relief cap and turn it slowly. Step back while the
pressure is released from the cooling system. When you are sure all the pressure has been
released, (still with a cloth) turn and remove the pressure relief cap.
CAUTION: Check the coolant and engine oil levels. Top off the coolant level if needed. If
there is engine coolant in the engine oil, the cause must be corrected and the oil changed or major component damage can occur. SECTION 303-

1. Verify the customer's concern by operating the engine to duplicate the condition.
2. Inspect to determine if any of the following mechanical or electrical concerns apply.
3. If the inspection reveals an obvious concern that can be readily identified, repair it as necessary.
4. Inspect the coolant condition. 1. WARNING: Never remove the pressure relief cap while the engine is
operating or when the cooling system is hot. Failure to follow these instructions
can result in damage to the cooling system or engine or personal injury. To avoid
having scalding hot coolant or steam blow out of the degas bottle when removing
the pressure relief cap, wait until the engine has cooled, then wrap a thick cloth
around the pressure relief cap and turn it slowly. Step back while the pressure is
released from the cooling system. When you are sure all the pressure has been
released, (still with a cloth) turn and remove the pressure relief cap.
Allow the engine to cool. Once pressure is released, remove the pressure relief cap.
2. CAUTION: Check the coolant and engine oil level and top off the coolant if
needed. If there is engine coolant in the engine oil the cause must be corrected
and oil/fluid changed or major component damage can occur.
